Sunday night's 24th annual Screen Actors Guild Awards isn't just about honoring the best in movies and TV. Even if you don't know a "Lady Bird" from a "Big Sick," you can still ponder the night's unique fashion choices.

Fans and professional critics alike are weighing in on the best and worst in attire among the celebrities arriving on the red carpet at the Shine Auditorium in Los Angeles, where the two-hour awards show is being televised live at 8 p.m. Eastern on TNT and TBS.

The SAG Awards, hosted by the SAG-AFTRA union at the Shrine Auditorium in Los Angeles, follow the Golden Globes as another major precursor to the 2018 Oscars.

The night after the 2018 Women's March, actress Kristen Bell ("The Good Place") will serve as the first-ever host of the SAG Awards alongside a slate of mostly female presenters.

"This is a unifying salute to women who have been very brave and speaking up," Kathy Connell, executive producer of the show, told The Hollywood Reporter.

The casts of the films "Lady Bird," "The Big Sick," "Get Out," "Mudbound" and "Three Billboards Outside Ebbing, Missouri" are among the nominees. So are the casts of the TV series "Stranger Things," "This Is Us," "The Handmaid's Tale," "The Crown" and "Game of Thrones."

Also among the nominees: actors James Franco and Aziz Ansari, who have both recently faced allegations of sexual misconduct or coercion. Both also won Golden Globes for their roles in "The Disaster Artist" and "Master of None," respectively.
